Antique Japanese Sword Tanto Attributed to Uda Kunifusa with NBTHK Hozon Certificate


This blade is attributed to Uda Kunifusa (宇多国房) during the late Nanbokucho era-Oei era (late 14th-early 15th century), according to NBTHK, which authenticated this blade.

Uda (宇多) is the prestigious school that flourished during the Nanbokuchoto-mid Muromachi period(approx. 1334-1491). It was founded by Kunimitsu(国光) in the late Kamakura period. The school was located in Etchu province in Toyama prefecture today. Kunimitsu was originally from Yamato Uda Gun(大和宇多郡), located in Nara prefecture but moved to Etchu in the late Kamakura period(1299-1333) with his apprentices including the first-gen Kunifusa(国房), and Kunimune(国宗).
The first-gen Kunifusa is the son of Kunimitsu and played an essential role for the school to flourish after they moved to Etchu province. The sword maker’s name, Kunifusa, lasted a few generations, and we believe it is attributed to the later-gen Kunifusa.

Uda school was famous for producing practically designed blades, which were desirable during Nanbokucho- Muromachi period. Among other schools in the Hokuriku region (the northwestern part of Honshu), Uda school was the most prominent school.
When the Uda school flourished in the Nanbokucho period, Japan was tumultuous because the imperial court was split into two sides(south and north). There were so many conflicts, and many Samurai were deployed.

There are two categories in the work of Uda school. One is called Ko Uda(Old Uda), and the other is Uda. Ko Uda swords were forged from the late Kamakura period to the Nanbokucho period. Uda blades were forged during the Muromachi period. This blade is categorized as a Ko-Uda blade.

This blade is appraised as a Hozon Token(保存刀剣) issued by NBTHK(Nihon Bijutsu Touken Hozon Kyokai:日本美術刀剣保存協会). This authentication paper was only given to authentic Japanese swords, well preserved with artistic value.

* Please keep in mind that there are a couple of black rust on Mune ( Backbone of the blade). We will be happy to have these parts polished by a professional Japanese sword polisher without additional charge before shipping this sword to you.

Curvature(Sori)0 cm( 0 inches)

NakagoNakago is the tang of the Japanese sword.

Japanese swordsmiths left the black rust on the tang because it prevents red rust while the tang is in its handle. And the discoloration of the tang was created over time, and it is a great indicator for a Japanese sword specialist to estimate when the sword was forged.

Koshirae: Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya(Scabbard), Tsuka(Handle), Tsuba(Handguard).


Fuchi-KashiraA pair of matching sword fittings that cover the upper and bottom parts of its sword hilt. 

This Fuchi Kashira has a simple look; black lacquer is painted, and it has finished in a plain design. Thanks to the lacquer technique, it has glossy black color. You will find that this Fuchi Kashira matches well when it is put into the handle.

Tsuka and MenukiTsuka is the handle of the Japanese sword and Menuki is its decoration.

This Menuki’s motif is probably a combination of seashells. It seems there are spiral shells and clams. In the Heian period, the Kaiawase (貝合わせ, a game that uses clams) became popular among aristocrats. Each clam matches only with its pair shell. Therefore, people consider that the clam pattern represents a happy marriage. It is said aristocracies once brought the kit of the Kaiawase as their trousseaux.

From another point of view, we could guess that the seashell motif has been familiar to Japanese people because of the geographical situation of Japan. Japan is an island, and several seas surround it. Therefore, the shipping industry is thriving, and seafood has been one of the essential food sources. From such a situation, we think that the seashell design was favored by many Japanese people, of course including Samurais.

KozukaKozuka is a small knife stored in Kozuka Hitsu(groove of the sheath of the Japanese sword).

The Kogatana (小刀, small knife) is stored in the Kozuka. A rooster is depicted. It seems gold paint was applied to its edge and the rooster. The surface of this Kozuka is decorated with tiny dots: it was made by hitting the Nanako-Ji Tagane (魚子地鏨, chisel used for this technique). It makes delicate fish egg-shaped protrusions. It gives the decorativeness for the work.

Authentication PaperNBTHK Hozon Certificate for the blade (No.3025228)

 NBTHK, also known as Nihon Bijutsu Touken Hozon Kyokai (the Society for the Preservation of the Japan Art Sword), is one of the oldest Japanese sword appraising organizations in modern-day Japan. They authenticated the blade on Feb 25th in the third year of Reiwa (2021). They appraised it as Hozon Touken, the blade worth preserving for Japanese society. The purchaser will receive this original certificate as well. We can also translate what is written into English and make a PDF file for your record if you request.
